M.A. Industries

What M.A. Industries does

M.A. Industries, Inc. is a privately held US manufacturer founded in July 1969 by Bob Peacock and headquartered at 303 Dividend Drive, Peachtree City, Georgia. The company originated with a hand-held injection-molded plastic "Mask Applicator" device for automotive masking tape and is recognized as the original plastic manhole step producer. Over its 55+ year history it has diversified into three operating divisions: Precast Supplies (manhole steps, cylinder molds, lifting devices, vault products), Consumer Porous Plastics (portable water bottle filters, fragrance dispensers), and Industrial Porous Plastics (flame arrestors for lead-acid batteries, mufflers, fluid delivery components, filters for power tools). Operations are organized horizontally across these three business units serving distinct end markets in the precast concrete, consumer goods, and industrial filtration sectors.

The company's core technology combines injection molding with proprietary porous plastics processing. It operates over 20 injection molding machines capable of producing 1,000 to 10 million parts per run using virgin or recycled polypropylene and polyethylene resins, with controlled pore sizes ranging from 10 to 350 micrometers and pore volumes of 30 to 70 percent. Cryogenic resin grinding supports custom resin and particle size tailoring. The Peachtree City facility is ISO 9001:2015 certified and committed to six sigma and lean manufacturing practices. An in-house M.A. Laboratory performs comprehensive testing and Statistical Quality Control on raw materials, while the engineering department runs CAD/CAM, 3D modeling, computer simulation, and in-house prototype and production mold making, enabling concept-to-production transitions in days. The company holds 27 patents and has accumulated 25+ years of porous plastics processing experience and 30+ years as a porous plastic filter manufacturer.

M.A. Industries operates a sales-led B2B model, selling directly to industrial customers without public pricing disclosure. It maintains satellite warehouses across all 48 contiguous US states to enable timely deliveries. The company is founder/family-owned (Peacock family), with Scott Peacock in current leadership, and has remained privately held with no disclosed institutional investor involvement. Customers are reached through three division websites (precast-supplies.com, porousplastics.com, maind.com) and a small named customer service team, with no named end-customer logos disclosed.

Core offering

M.A. Industries manufactures injection-molded plastic products through three divisions: Precast Supplies (manhole steps, cylinder molds, lifting devices, vault products), Consumer Porous Plastics (portable water filters, fragrance dispensers using wicking properties), and Industrial Porous Plastics (flame arrestors for lead acid batteries, mufflers, fluid delivery components, filters for power tools). Production is based at an ISO 9001-2015 facility in Peachtree City, GA with cryogenic resin grinding, in-house mold making, and capacity from 1,000 to 10 million parts.

Product overview

M.A. Industries is a multifaceted manufacturing company with three distinct divisions offering products for the precast concrete marketplace and porous plastic marketplace. The Precast Supplies Division provides Manhole Steps (their original core product), Cylinder Molds, Lifting Devices, and Vault Products, leveraging over 20 injection molding machines and in-house quality control through the M.A. Laboratory. The Consumer Porous Plastics Division offers Portable Water Bottle Filters and Fragrance Dispensers using porous plastic materials with activated carbon filtering properties for water filtration applications. The Industrial Porous Plastics Division produces Flame Arrestors for Lead Acid Batteries, Mufflers, Fluid Delivery Components, and Filters for Power Tools, utilizing proprietary porous plastic technology with controlled pore sizes ranging from 10-350 um and pore volumes of 30-70%. All divisions leverage cryogenic resin grinding capabilities to tailor resins and particle sizes to customer requirements.
